Are you referring to this? If so, where does it say that CIA approved the changes?

Mr. Petraeus, who resigned last week after admitting to an extramarital affair, said the names of groups suspected in the attack — including Al Qaeda’s franchise in North Africa and a local Libyan group, Ansar al-Shariah — were removed from the public explanation of the attack immediately after the assault to avoiding alerting the militants that American intelligence and law enforcement agencies were tracking them, lawmakers said.

The talking points initially drafted by the C.I.A. attributed the attack to fighters with Al Qaeda in the Islamic Maghreb, the organization’s North Africa franchise, and Ansar al-Shariah, a Libyan group, some of whose members have Al Qaeda ties.

Mr. Petraeus and other top C.I.A. officials signed off on the draft and then circulated it to other intelligence agencies, as well as the State Department and National Security Council.

At some point in the process — Mr. Petraeus told lawmakers he was not sure where — objections were raised to naming the groups, and the less specific word “extremists” was substituted.

He said it in his testimony yesterday.
